The ultimate otaku teacher, Junichiro Kagami, is back with his unique group of students. But as the school year goes on, things start to get...spooky!

When tasked to clean out the old dorms, Kagami and his students stumble upon the ghost of a former classmate. All she wants to do is pass on to the next life but is having a little trouble. Are they up for this spiritual lesson? Things heat up when conflict arises between a gang leader and pop idol. Are street smarts more important than school smarts? Once things start to calm down, even Kagami's most troubled students start settling into better lives.

Realizing that he's neglected things he used to care about like his blog, figurines, and anime, Kagami begins to question if teaching is where he truly belongs. When the opportunity to work on his Anywhere Door arises, he'll have to make a tough choice. What does Kagami really yearn to do: teach or research!?
